Please some quotes from His Holiness Pope Shenouda III’s Book: The Spirituality of Fasting: Fasting is a gift
When we realise the benefits of fasting, we find that it is a blessing from God.
Yes, fasting is not merely a commandment from God but a godly gift, a grace and a blessing. God the creator of our body and soul knows of our need to fast for its benefit for our spiritual life, development and our eternity. He granted us the knowledge and manner of fasting. As a kind Father and a wise Teacher, He has recommended fasting for us.
Fasting is not hunger for the body but nourishment for the soul.
Fasting, as some people speculate, is not a bodily torture, martyrdom, or a cross, but it is a way to elevate the body to reach the level of cooperation with the soul. When we fast, our intention is not to torture the body but to shun its behaviour. Thus, one who fasts becomes a spiritual and not a physical person. Fasting is an ascetic soul which takes the body with it as its partner in asceticism.
